To aZZ whom it may concern:

Be it known that we, SAMUEL S. MARCUS and SAMUEL KRAKAUER, citizens ofthe United States, and residents of the city of New York, borough of theBronx, in the county of Bronx andState of New York, have invented a newand Improved Covered Spring Structure, of which the following is a full,clear, and exact description.

This invention has relation to covered spring structures and hasparticular reference to cushion seat or bed spring structures whichinclude a plurality of coiled springs placed side by side to form aresilient element.

As an object the invention contemplates in a covered spring structure,means for maintaining the individual spring elements under compression,said means also servii'ig to insulate the convolutions of said elementsfrom each other to prevent clashing or knocking of the same against theconvolutions of contiguous elements.

As a further object the invention contemplates means for holding thespring ele ments under compression which also serves as means forholding the individual spring elements in contiguous relation and foreliminating the release of the same from their initial or normalcompression in event of the breakage or displacement of the holdingclips.

As a further object the invention contemplates a simple and effectivemeans for associatingthe individual elements of a spring seat structure,which means renders the manufacture and production inexpensive as wellas strong and durable.

'VVith the above recited and other objects in view, the inventionresides in the novel construction set forth in the following specification, particularly pointed out in the ap-- pended claims andillustrated in the accompanying drawings, it being understood that theright is reserved to embodiments other than those actually illustratedherein to the full extent indicated by the general meaning of the termsin which the claims are expressed.

In the drawings- Figure 1 is a fragmentary plan view of a springstructure embodying the invention.

Fig. 2 is a sectional view therethrough taken approximately on the line2-2 of Fig. 1. V

Fig. 3 is a transverse f agment ry secarranged contiguous to each otherto make up a spring structure'to be employed as a bed spring, or cushionseat structure. It has been definitely established that cushion springswhen l'rept'under compression are superior inaction to thosethat are notso kept, and't-he inventiontherefore relates to the means for connectingthe springs 10 to each other and the manner in whichv the same are heldunder an initial or normal compression. As illustrated a strip of fieible material 11 is connected at one extremity by means of a clip12- tothe upper end convolution of one of the springs 10 and is then passeddownwardly toward the opposite end and under the same where it issecured at diametrically opposite points by the clips 12 to the lowerend convolution of said spring 10. The strip is then alternatelythreaded upwardly and over the upper end convolutions and downwardly andunder the lowerend convolutions of the adjacent springs 10 in asubstantially sinuous path. At each point of change of direction of thestrip. the same is secured by one of the clips 12 to the springconvolution with which it engages. The contiguous convolutions ofadjacent springs 10 are retained in juxtaposition by means of the clip12 which attaches the strip to the spring. In the next adjacent row ofsprings, the strip is alternately threaded over and under the springsections in a substantially sinuous course or path as illustrated, andin attaching the contiguous upper and lower convolutions of the springsections of adjacent rows a strip 13 is connected at its upper and lowerends respectively to the convolutions of the spring sections of theadjacent rows by means of the clips 12 which attach the rows together.This construction interposes what may be termed an insulating stripbetween the convolutions to prevent clashing or interference f theintermediate convolutions with each other when weight is brought to bearon the structure. The sinuous arrangement of the strips 11 interposesbetween the contiguous spring sections 10 of each row an insulatingportion for a like purpose and said sinuous threading of the stripserves to hold the springs under the/initial or nor mal compression eventhough one or more of the clips 12 should be broken or detached.

We claim:

1. In combination, a covered spring structure embodying a plurality ofrows of contiguous spring sections, and a common means for holding thesame under partial compression and for insulating the convolutionsthereof from each other, comprising a strip of flexible materialconnected at one extremity to one of the end convolutions of an endspring section and passed alternately under and over the spring sectionsof each row, and means for securing the strips at diametrically oppositepoints to the end convolutions. 7

2. In combination, a covered spring structure embodying a plurality ofrows of contiguous spring sections, and a common means for holding thesame-under partial compression and for insulating the convolutionsthereof from each other, comprising a strip of flexible materialconnected at one extremity to one of the end convolutions of an endspring section and passed alternately under and over the spring sectionsof each row, and means for securing the strips at diametrically oppositepoints to the end convolutions, said means of securement serving to alsoconnect the spring sections in contig uous relation.

3. In combination, acovered spring structure embodying a plurality ofrows of contiguous spring sections and a common means for holding thesameunder partial compression and for insulating the convolutionsthereof from each other, comprising a strip of flexible materialconnected at its opposite ends respectively to an end convolution of theend spring and alternately passed under and over the intermediate springsections of each row, and means for securing the intermediate portionsof the strip to the end convolutions respectively at its points ofcontact therewith.

l. In combination, a covered spring structure embodying a plurality ofrows of contiguous spring sections and a common means for holding thesame under partial compres sion and for insulating the convolutionsthereof from each other, comprising a strip of flexible materialconnected at its opposite ends respectively to an end convolution of theend spring and alternately passed under and over the intermediate springsections of each row, means for securing the intermediate portions ofthe strip tothe end convolutions respectively at its points of contacttherewith, and means for connecting the contiguous points of the endconvolutions of the spring sections of the adjacent rows and forinsulating the convolutions thereof comprising a single vertical stripof a length approximately equal to the height of a spring section andpassing between adjacent spring sections, the upper end of said stripbeing connected to adjacent parts of the contiguous upper convolutionsand the lower end being connected to adjacent parts of the lowercontiguous convolutions.
